Steps to install jQuery in Nuxt.js

Question

Although I tried adding jQuery to my project, I encountered an error saying it was undefined.

plugins: [
    { src: '~/plugins/js/svgSprite.js', mode: 'client' },
    { src: '~/plugins/vendor/jquery/jquery.min.js', mode: 'client' },
    { src: '~/plugins/vendor/bootstrap/js/bootstrap.bundle.min.js', mode: 'client' },
    { src: '~/plugins/vendor/bootstrap-select/js/bootstrap-select.min.js', mode: 'client' }, <-- 给我报错
    { src: '~/plugins/vendor/magnific-popup/jquery.magnific-popup.min.js', mode: 'client' },
    { src: '~/plugins/vendor/smooth-scroll/smooth-scroll.polyfills.min.js', mode: 'client' },
    { src: '~/plugins/vendor/object-fit-images/ofi.min.js', mode: 'client' },
    { src: '~/plugins/js/theme.js', mode: 'client' }
  ],

Why this happens, obviously I have declared jQuery before bootstrap-select.

I do not recommend adding jQuery to Nuxt projects.

But if you really want to add it, you can follow the steps below:

• Use yarn add jqueryInstall it
• Add the following to your nuxt.config.js file

import webpack from 'webpack'

export default {
  // ...
  build: {
    plugins: [
      new webpack.ProvidePlugin({
        $: 'jquery',
        jQuery: 'jquery',
        'window.jQuery': 'jquery'
      })
    ]
  },
}

• Make sure your .eslintrc.js file has the following content

module.exports = {
  // ...
  env: {
    // ...
    commonjs: true,
    jquery: true
  },
}

Then, you can use it like this in method or similar

$("h2").addClass("tasty-class")
